    Thanks for this, I've been using Node-red for years but nice to be reminded of the basics and also the newer Node-red changes.

    To elaborate: Store data at 00:00, 00:01, 00:02, 00:03,..................23:00: and full day delta for kwh_produced, kwh_consumed, gas_consumed.

      Do you prepared any video that can help storing data having multiple fields on the same topic? How I can store different fields in influxdb via node red. Now I’m able to store single value

    Hi Csongor, nice videaos and keep up the effort.
    I have used the storing of data in csv files and it works great. For Sensors t his is great. I have a MQTT with meterdata and want to only store at the whole hr and at 00:00 Can there be a time/data functionality be added?

    • @csongorvarga
      @csongorvarga  Год назад

      Thanks. Yes, there is an option. Store the data that comes in from the MQTT node in a flow variable. And have a separate inject node that runs every hour and fetch the data from the flow variable. It will contain the latest data as new data always overwrites the one came before.

    how do you start the mqtt server in node read?

    • @csongorvarga
      @csongorvarga  2 месяца назад

      You don't. MQTT server is completely different from Node-Red. That needs to be installed separately.

    "Connecting to the MQTT broken" on the contents should be broker, probably :)

  • @mohsinjessa8951
    @mohsinjessa8951 Год назад

    Just started watching this video...and first suggestion...first slide "Content" line "Connecting to the MQTT Broken" change broken to broker.

    Hi why is my mqtt in just keep connecting

    • @csongorvarga
      @csongorvarga  Год назад

      On the right when you see your debug, go to the Configuration Nodes and check to make sure you don't have duplicate configuration for the same MQTT server. I had this issue once.

    Way to much elaboration or unnecessary details
